2 Comfort objectief beoordelen: kan dat echt? Àngels Cornellana Morros, Product Marketing Manager, Teijin Aramid

3 Comfort objectief beoordelen: kan dat echt? Is comfort vandaag nog luxe of eerder basis? Wat is eigenlijk comfort? Wat zijn de verschillende factoren die bepalen of een kledingstuk als comfortabel ervaren wordt? Hoe kan je deze ook meten en vergelijken? Hoe kan je comfort meenemen als objectieve parameter bij de selectie van een kledingpakket?

4 Why is comfort important? Discomfort can lead to increased risk and discontent of your people Comfort influences whether workers wear protective clothing > 80% of workers have observed other workers not wearing protective clothing Top reasons: uncomfortable and too hot Why should comfort be of consideration? Increase compliance More likely to wear Increase productivity and reduce breaks Reduce illness Increase worker moral and decrease discontent Is comfort nowadays still a luxe or is it a basic requirement? Conclusion: you don t need to sacrifice comfort! Nowadays you can be both protected and comfortable at the same time.

5 What is comfort? Shape Air permeability Smoothness Perspiration smell Warm/Cool Feeling Colorfastness Breathability Water absorbency capacity Softness Insulation Pilling Shininess Drying rate comfort Wrinkle resistance and recovery Flexibility / Stretch Volume/Thickness Sweat visibility Wickability Drapability Stain release Water resistance & Water proofness Hairiness Weight Water repellency Wet stickiness

6 What is comfort? Climate & Moisture Management Wickability Drying rate Air permeability Breathability Insulation Water resistance & Water proofness Water repellency Water absorbency capacity Touch/Hand Feel Smoothness Volume/Thickness Softness Warm/Cool Feeling Drapability Hairiness comfort Ease of Movement Weight Wet Stickiness Flexibility/Stretch Shape Appearance Colorfastness Pilling Wrinkle resistance and recovery Transpiration smell Sound Shininess Drapability Stain release Sweat visibility

7 What is comfort? Developed together with VDP (end-user information) and using research / test labs (TA)

8 Touch/Hand Feel (Sensorial Comfort)

9 Touch/Hand Feel Which factors can be measured? Smoothness Volume/thickness Softness Warm/Cool Feeling Drapability Hairiness

10 Touch/Hand Feel How to measure Comfort? Smoothness Softness Definition: Surface friction - slippery <> harsh (rough) Test method: Friction force, resistance to sliding of two surfaces in contact. ISO 8295, ASTM D1894 Definition: Ease of bending (pliable) <> stiff Test method: Cantilever stiffness test (bending rigidity), ISO 53362

11 Touch/Hand Feel How to objectively compare Comfort? Smoothness Softness

12 Appearance (Aesthetic Comfort) Why is appearance important? Clothing serves as visit card of your company Clothing represents the pride of the wearer

13 Appearance Which factors can be measured? Colorfastness Drapability / stability Pilling Transpiration smell Wrinkle resistance and recovery Sweat visibility Stain release Luster / dullness (Shininess) Sound

14 Appearance How to measure Comfort? Colorfastness Drapability / stability Pilling Transpiration smell Wrinkle resistance and recovery Sweat visibility Stain release Definition: Resistance to color change under specified conditions, such as exposure to a bleach solution, abrasive wear and rubbed. Test method: Washing: ISO 0105,C10 Light: ISO 105,B02 Perspiration: ISO 105, E04 Rubbing: ISO 105, X12 Definition: The ability of a textile to resist bending and the formation of wrinkles and/or to return to a flat state. Test method: ISO 2313 Luster / dullness (Shininess) Sound Definition: The specular and diffuse reflection of incident light from a textile surface Test method: Reflection of light

15 Climate & Moisture Management (Thermophysiological Comfort) What do you wear when you sport? Cotton or Polyester? Cotton T-shirts Feel comfortable Once you sweat, you get completely wet, and they remain wet Reason: cotton is extremely hydrophilic, holding up to 25 times its weight in water, and takes an exceptionally long time to dry Once wet, cotton can lead to chafing in hot weather, and hypothermia in cold weather Polyester T-shirts Feel cool Don t feel wet when you sweat Release moisture (move sweat from the body) quicker Dry quicker and have more ventilation

16 Climate & Moisture Management Which factors can be measured? Wickability Drying rate Air permeability Breathability Water absorbency Water repellency Water resistance and water proofness Insulation

17 Climate & Moisture Management How to measure Comfort? Wickability Drying rate Air permeability Breathability Water absorbency Water repellency Water resistance and water proofness Insulation Definition: Ability to take water internally into fibers Test method: ISO Remark: If a fabric a can absorb water, the material can swell during the wicking. If the fabric swells, the capillary pores will be reduced and the wicking rate will be reduced.

18 Climate & Moisture Management How to measure Comfort? Wickability Drying rate Air permeability Breathability Definition: Spread of water through a fabric, by capillary action. Test method: Vertical Wicking : AATCC 197 Horizontal Wicking: AATCC 198 Remark: Wickability is desirable in garments worn in hot environments, where high temperatures cause sweating. Wet fabric tends to cling, places a greater burden on motion, and is more abrasive than dry fabric Water absorbency Water repellency Water resistance and water proofness Insulation Definition: Time necessary for a fabric to dry. Test method: ISO 17617:2014 Remark: A fabric that remains wet cools down the body more than a fabric that dries quickly. Wet fabric tends to cling, places a greater burden on motion, and is more abrasive than dry fabric.

19 Climate & Moisture Management How to objectively compare Comfort? Wickability Drying rate Air permeability Breathability Water absorbency Water repellency Water resistance and water proofness Insulation

20 Climate & Moisture Management How to measure Comfort? Wickability Drying rate Definition: The degree to which a fabric allows air to pass through its construction. Air permeability Breathability Test method: ISO 9237 Remark: Air permeability is critical to the fabrics breathability. It enables heat and moisture vapor transmission. Water absorbency Water repellency Water resistance and water proofness Insulation

21 Climate & Moisture Management How to objectively compare Comfort? Wickability Drying rate Air permeability Breathability Water absorbency Water repellency Water resistance and water proofness Insulation

22 Ease of movement (Body-movement Comfort) Why is ease of movement important? Freedom of movement Restriction in motion / in doing the job

23 Ease of movement Which factors can be measured? Weight Flexibility/Stretch Wet Stickiness Shape

24 Ease of movement How to measure Comfort? Definition: Mass per unit area (gsm or osy) Weight Flexibility/Stretch Test method: ISO 3801 (ASTM D3776) Remark: Volume/Thickness/Weight determines the amount of burden to be carried by the wearer. Lightweight fabrics are considered important garment comfort features. Wet Stickiness Shape Definition: The ability of textile to extend under tension and then to recover relatively quickly and fully to its original dimensions. Test method: Stretch JIS L 1096 method B (ASTM D ), ISO Remark: Fabric must elongate to accommodate body movement and then recover to its original dimensions.

25 Ease of movement How to objectively compare Comfort? Weight Flexibility/Stretch Wet Stickiness Shape

26 Ease of movement How to measure Comfort? Definition: Fore required (resistance) to move a textile fiber over a wet surface Weight Test method: Teijin test method: Determination of stickiness for textile fabrics. Flexibility/Stretch Wet Stickiness Shape Remark: The friction (resistance) change if moisture is present in the fabric-skin interface. Definition: Ability of a textile to produce a compressive force sufficient to permit wearer comfort and body shaping. Test method: Wear trial, users feedback.

27 Conclusion Comfort can be objectively assessed There are various factors that determine whether a garment is perceived as comfortable Touch/Hand Feel Ease of Movement Appearance Climate & Moisture Management You can now include comfort as an objective parameter when selecting a clothing package But, comfort depends on the situation. The best you can do is ask for a wearing test.

28 Conclusion Comfort can be objectively measured Conclusion for Protective Apparel: Contrary to common belief, there s no need to choose between comfort and safety in protective workwear FR durable workwear is now comfortable with Teijinconex Coolnex Fabrics Super Wicking: Athletic performance through moisture management Try it yourself!
